The Lincoln Electric KP4523-1-75F is a premium gas nozzle designed specifically for the Magnum PRO series of water-cooled semi-automatic welding guns. Engineered to meet the rigorous demands of heavy industrial fabrication, this nozzle is compatible with both the Magnum PRO 400A and 500A water-cooled models. As a critical component in the shielding gas delivery system, it ensures laminar flow and robust protection of the weld pool, even under high-amperage conditions typical of water-cooled applications.
This specific nozzle features a Flush tip geometry. Flush nozzles are often preferred when the welder requires a balance between gas coverage and contact tip accessibility. Unlike recessed nozzles, which are ideal for longer stick-outs, or protruding nozzles used for tight corners, the flush design brings the contact tip level with the nozzle exit. This configuration is excellent for maintaining a consistent arc length and provides better visibility of the puddle in general welding positions. The flush design also helps prevent the accumulation of spatter inside the nozzle bore, as the tip is not hidden deep within the cup.
With a large 3/4-inch (19.1 mm) Inner Diameter (ID), this nozzle is built for high-deposition welding. The wide bore allows for a substantial volume of shielding gas to cover the weld zone, which is essential when welding with larger diameter wires or at higher travel speeds. The larger opening also reduces the frequency of cleaning required, as it takes longer for spatter to bridge the gap between the contact tip and the nozzle wall. Constructed from high-grade materials, the KP4523-1-75F withstands the intense radiant heat generated during continuous welding, ensuring longevity and reducing downtime for consumable changes.
